NS-NF1Dynamic Fiber Optic Gyro North Finder

1.Introduction:

The NS-NF1 Dynamic Fiber Optic Gyro North Finder is a high-precision inertial instrument with autonomously indicating azimuth. It can give the angle between the carrier and the true north direction without inputting the latitude value.

The angular value of the earth's rotation measured by the fiber optic gyroscope and the angle between the gyroscope and the horizontal plane measured by the accelerometer are calculated by computer to obtain the angle between the baseline of the carrier and the true north direction, thereby obtaining the value of the azimuth of the carrier. The accelerometer at the baseline measures the attitude angle of the north finder.

The fiber optic gyroscope used in the fiber optic gyro north finder is composed of a fiber ring, a semiconductor laser, a Y-waveguide, etc. They are solid-state devices and have no rotating parts, so that the device can withstand impact and vibration. This is something that other non-fiber optic gyroscopes can't do.

2.Product features:

NS-NF1 dynamic fiber optic gyro north finder is based on high-precision fiber optic gyroscope and quartz accelerometer as the core components, mainly composed of inertial measurement unit, data acquisition and processing unit, precision indexing mechanism and control display unit, etc. Features such as GPS/GNSS/BD receiver, odometer sensor, altimeter and star sensor can be added to provide the azimuth of the carrier and true north, as well as the motion attitude, speed and position information of the carrier.

3.Applications

1)missile launch

2）weapon aiming

3）dynamic and static initial alignment and direction control of radar, antenna, vehicle and other objects.
